Exploring the ultra-faint dwarf Bootes I using JWST and HST: Metallicity distribution and binaries
F. Muratore, M. V. Legnardi, A. P. Milone +8
Ultra-faint dwarf galaxies (UFDs) are among the oldest and most metal-poor stellar systems in the Universe. Their metallicity distribution encodes the fossil record of the earliest…
Tracing ωCentauri's origins: Spatial and chemical signatures of its formation history
E. Dondoglio, A. P. Milone, A. F. Marino +8
ω}Centauri (ωCen) is the most enigmatic Galactic globular cluster (GC), with unmatched chemical complexity. We combine photometric and spectroscopic catalogs to identify its distin…
The Small Magellanic Cloud through the lens of the James Webb Space Telescope : binaries and mass function within the galaxy outskirts
M. V. Legnardi, F. Muratore, A. P. Milone +8
The stellar initial mass function (IMF) and the fraction of binary systems are fundamental ingredients that govern the formation and evolution of galaxies. Whether the IMF is unive…
Hunting for UVdim stars in Galactic Open clusters. Clues from ultraviolet photometry
G. Cordoni, A. P. Milone, L. Casagrande +7
Split main-sequences (MSs) and extended main-sequence turn-offs (eMSTOs) have been observed in nearly all Magellanic Clouds clusters younger than 2 Gyr. More recently, Hubble Space…
SN 2024aecx: A double-peaked rapidly evolving Type IIb supernova at 11 Mpc
Xingzhu Zou, Brajesh Kumar, Rishabh Singh Teja +28
We present the results of low-resolution spectroscopic and densely sampled multi-band photometric follow-up of supernova (SN) 2024aecx. The SN was discovered in the spiral galaxy N…
A JWST project on 47 Tucanae. Binaries among multiple populations
A. P. Milone, A. F. Marino, M. Bernizzoni +25
Almost all globular clusters (GCs) contain multiple populations consisting of stars with varying helium and light-element abundances. These populations include first-population sta…
Linking Photometry and spectroscopy: profiling multiple populations in globular clusters
E. Dondoglio, A. F. Marino, A. P. Milone +14
Our understanding of multiple populations in globular clusters (GCs) largely comes from photometry and spectroscopy: appropriate photometric diagrams can disentangle first and seco…
Exploring the formation environment of multiple stellar populations in Globular Clusters through binary systems
E. Bortolan, J. Bruce, A. P. Milone +9
Globular Clusters (GCs) are known to host distinct stellar populations, characterized by different chemical compositions. Despite extensive research, the origin of these population…
Mass loss along the red giant branch of the intermediate stellar populations in NGC6752 and NGC2808
M. Tailo, A. P. Milone, A. F. Marino +15
The morphology of the Horizontal Branch (HB) in Globular Clusters (GC) is among the early evidences that they contain multiple populations of stars. Indeed, the location of each st…
New perspective on the multiple population phenomenon in Galactic globular clusters from a wide-field photometric survey
S. Jang, A. P. Milone, A. F. Marino +10
Wide-field photometry of Galactic globular clusters (GCs) has been investigated to overcome limitations from the small field of view of the Hubble Space Telescope in the study of m…
A JWST project on 47 Tucanae: kinematics, energy equipartition and anisotropy of multiple populations
T. Ziliotto, A. P. Milone, G. Cordoni +17
Recent work with JWST has demonstrated its capability to identify and chemically characterize multiple populations in globular clusters down to the H-burning limit. In this study,…
